Import 54.6v 54ah Li-Ion Battery Lithium Battery Pack — Buy in wholesale FOB from Supplier in China

This 54.6V 54Ah lithium-ion battery pack is constructed from rechargeable cells arranged to deliver a nominal 54.6 volts at 54 ampere-hours capacity, representing approximately 2.95 kWh of stored energy. The 54.6V charge voltage indicates a 15-cell series configuration if using lithium cobalt oxide (LCO) or lithium nickel manganese cobalt oxide (NMC) chemistry with a 4.2V per cell ceiling, or a 16-cell series if based on lithium iron phosphate (LiFePO4) with a 3.65V per cell charge voltage. The supplier notes suitability for electric vehicles, robotics, solar energy storage, and industrial equipment, though the specific cell chemistry, cycle life rating, and continuous discharge rate are not stated in the source data and should be confirmed directly.

The pack construction typically incorporates a battery management system (BMS) to manage cell balancing, overcharge protection, over-discharge cutoff, and thermal monitoring. Standard industry practice for packs of this voltage class includes MOSFET-based protection with typical current limits of 50-100A continuous, though the actual rating depends on application and cell selection. The enclosure is likely an aluminium extrusion or ABS/polycarbonate case with IP54 or higher ingress protection, but the exact IP rating, cooling method (passive, forced air, or liquid), and communication protocol (CAN, RS485, or SMBus) are not specified. Cell format may be cylindrical (18650 or 21700), prismatic, or pouch, each affecting volumetric energy density and thermal behaviour differently.

Target buyers include electric vehicle manufacturers, solar integrators, robotics firms, and industrial equipment OEMs requiring high-voltage energy storage. The supplier mentions flexible minimum order quantities, but no figure is provided on this listing. International certifications such as ISO and CE are referenced, though the specific standards (UN38.3 for transport, IEC 62619 for industrial use, or UL 1973 for stationary storage) and test report numbers should be requested. Payment terms and shipping options are not detailed in the source material, so direct negotiation with Grace Battery Technology Development Co., Ltd is necessary to establish Incoterms, payment structure, and warranty terms for this Shanghai-based supplier.

Grace Battery Technology Development Co., Ltd is located at Room 101B, Building 16, No. 481 Guiping Road, Xuhui District, Shanghai 200000, China. The company is classified at the 'harbor' trust tier. Response rate and average response hours are recorded as zero, indicating no response data has been accumulated rather than an active zero response rate. This absence of communication history means buyers should initiate contact to assess technical competence, English language capability, and engineering support availability before committing to development contracts or volume orders.

The listing does not state founding year, factory ownership model (OEM, ODM, or trading company), production capacity, number of employees, annual revenue, named clients, or specific quality certifications beyond general references to ISO and CE compliance. Shanghai's battery industry includes both cell manufacturers and pack assemblers, so it is important to clarify whether Grace Battery produces cells in-house or sources them from tier-one cell makers such as CATL, BYD, or EVE. The exact scope of their BMS design capability, whether in-house or outsourced, and their testing infrastructure (charge/discharge cyclers, environmental chambers, vibration tables) should be verified through direct enquiry or factory audit.
